In view of the problem of water pollution in Shahe River,we analyze the surrounding pollution sources of Shahe River.The main sources of pollution are 24 drainage outlets along the coast,tail water of sewage treatment plant,surface runoff and the release of contaminated sediment.Based on the distribution characteristics of the Shahe River pollutant,we put forward some measures such as controlling the pollution of the source and removing the pollution,improving the standards of the pollution treatment,removing the endogenous pollutions,restoring the ecosystem,diverting water and so on to reduce the pollution and repair the water ecosystem.After the implementation of the project,the black and odorous water of Shahe River has been recently eliminated,and the long-term main indexes reach the standard of surface water IV.
